Items in Grasspers aren't items in world, so they're not laggy on the server. Possibly a compatibility config option that defaults to off, so that people experience <sarcasm>glorious in-world dropping of hundreds of items*</sarcasm> first.

*I don't have issue with it, but many apparently do, with it not working or working badly.

On the non-flora side of the suggestion, there's TC4's Arcane Pedestals, which could've used for that as well.

No, I have no intention of doing this, I like the item movement mechanic. I understand that it can cause lag on large servers, but I'm not going to deliberately dumb down the mod just to allow hundreds of people to play at once.

Lag on not-even-large-conjuration-endoflame-array-is-comparable-with-boundpick-mining servers, gets blocked from working by any Magnetism effect or area item pickup nearby, causes everyone to just slap down Thermalilies which you grump on.
